Access private member of enclosing class from nested one

[Fedor Rodikov]

Could anybody explain me how the following code snippet is compiled?
According to the paragraph 11.8 of C++ standard the nested and
enclosing
classes obey usual access rules, but my compiler doesn't complain.

struct A
{
void foo()
{
B::bar1();
B::bar2( *this );
}

struct B
{
static void bar1()
{
init1();
}
static void bar2( A& a )
{
a.init2();
}
};

private:
static void init1() {}
void init2() {}
};

int main()
{
A a;
a.foo();
}

Thanks in advance!

Access rules for nested classes have been recognized as a language defect:

Your compiler aparently implements the proposed resolution, which is also
reflected in the wording of the proposal n3291 for C++0X.
